Article Synopsis
- This study focuses on finding safe ways to stop fungi from damaging old manuscripts that are really old, like from the 13th century.
- Researchers found and tested different types of fungi that were causing the damage, like Aspergillus niger and Penicillium citrinum, to understand how they work.
- They discovered that a natural bacteria, Lactobacillus plantarum, can help stop these harmful fungi, and figured out that using a specific concentration of ethyl acetate extract is safe and effective for protecting valuable paper.
The main hypothesis of the present research is investigating the efficacy of titanium oxide nanoparticles (TiO-NPs) to prevent the growth of fungal strains when applied on leather under an experimental study. Therefore, fifteen fungal strains were isolated from a deteriorated historical manuscript (papers and leathers) and identified by traditional methods and ITS sequence analysis, including (one isolate), (two strains), (four strains), (one strain), (one strain), (two strains), (two strains), and (two strains). The enzymes cellulase, amylase, pectinase, and gelatinase, which play a crucial role in biodegradation, were highly active in these fungal strains.

The obtained fungal strains were identified, using the traditional method and ITS sequence analysis, as (two strains), (five strains), (one strain), (two strains), (one strain), and (one strain). The ability of these fungal strains to degrade the main components of the paper was investigated by their activity to secrete extracellular enzymes including cellulase, amylase, gelatinase, and pectinase.

The study aims at the exploration of the role of various fungal strains that had colonized this deteriorated manuscript in its biodeterioration through their efficacy in the secretion of various hydrolytic enzymes. To evaluate the deterioration, various techniques, including visual inspection, attenuated total reflectance Fourier transform infrared (ATR-FTIR), scanning electron microscopy (SEM), X-Ray diffraction analysis (XRD), color change, and pH value, were utilized.

While Egyptian mummies have undergone CT scans in prior studies, a systematic survey of the orthopedic conditions afflicting a group of these ancient individuals has never been carried out.
Methods: We performed whole body CT scanning on 52 ancient Egyptian mummies using technique comparable to that of medical imaging.
